epwar - They've proven to be irrelevant any time in the past when he faced top competition, so the answer is: YES!
Fedor got Datsik-mounted by a man who was submitted by a Sherdog staff member. When this is the kind of thing that happens in the real world I guess your fragile psyche needs a crux like this MMAth barcode battler stuff to protect itself from the reality of people actually fighting.
bottom line on werdum is that he is not a machine, not unbeatable but he's got some solid wins in his career that the fedor haters are overlooking.
shane carwin's sole legit win over a top opponent is gonzaga. well, guess who's also beat gonzaga by finish? tapping aleks in quick fashion is no joke and werdum also had very close fights with arlovski and kharitonov (both fights were very similar actually).
